Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 11,273,465, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 11,273,465 | |
| -1 | -11,273,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,273,465.
Example:
1 x 11,273,465 = 11,273,465
and
-1 x -11,273,465 = 11,273,465
Notice both answers equal 11,273,465
With that explanation out of the way, let's continue. Next, we take the number 11,273,465 and divide it by 2:
11,273,465 ÷ 2 = 5,636,732.5
If the quotient is a whole number, then 2 and 5,636,732.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 11,273,465 | |
| -1 | -11,273,465 |
Now, we try dividing 11,273,465 by 3:
11,273,465 ÷ 3 = 3,757,821.6667
If the quotient is a whole number, then 3 and 3,757,821.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 11,273,465 | |
| -1 | -11,273,465 |
Let's try dividing by 4:
11,273,465 ÷ 4 = 2,818,366.25
If the quotient is a whole number, then 4 and 2,818,366.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 11,273,465 | |
| -1 | 11,273,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 18,947 | 94,735 | 132,629 | 322,099 | 663,145 | 1,610,495 | 2,254,693 | 11,273,465 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -18,947 | -94,735 | -132,629 | -322,099 | -663,145 | -1,610,495 | -2,254,693 | -11,273,465 |
